Description

Technical Field

[0001] This utility model belongs to the technical field of grinding equipment and relates to a dual-power grinding and separation device. Background Technology

[0002] Currently, grinding machines are mainly divided into vertical stirred grinding machines, horizontal disc grinding machines, and horizontal pin grinding machines, which are widely used in various industries such as coatings, inks, pesticides, mining, and ceramics. However, current grinding machines mainly suffer from technical problems such as high energy consumption, low efficiency, excessively high temperatures, and low grinding quality. With the widespread application of new energy sources and nanomaterials, higher requirements are being placed on the grinding quality, grinding efficiency, and service life of grinding machines.

[0003] Existing grinding equipment has many drawbacks, such as the single-shaft drive causing the grinding and separation speeds to restrict each other, making it difficult to meet the needs of different material characteristics; static screen separation is prone to clogging, and the separation accuracy is only 10-20μm, which cannot meet the requirements of high-end material processing.

[0022] Please refer to Figure 1 The embodiments of this application include: a dual-power grinding and separation device, comprising: a main drive system and a separation drive system;

[0023] The main drive system includes: main shaft 1, main bearing housing 4, main V-belt pulley 2, pin rotor 9, grinding inner cylinder 8, grinding outer cylinder 10, and main machine mechanical seal 6;

[0024] The spindle 1 is mounted on the main bearing housing 4 via bearings, and is mounted on the machine body via the main bearing housing 4. A main machine mechanical seal 6 is provided at the connection between the spindle 1 and the machine body.

[0025] One end of the main spindle 1 is fixedly mounted with the main V-belt pulley 2 via a key connection or interference fit, and the main motor drives the main spindle 1 to rotate through the main V-belt pulley 2.

[0026] The pin rotor 9 is fixedly installed on the other end of the main shaft 1. The inner grinding cylinder 8 and the outer grinding cylinder 10 cooperate to form a grinding cavity; the pin rotor 9 is located inside the grinding cavity.

[0027] The separation drive system includes: separation spindle 19, separation bearing housing 14, separation V-belt pulley 17, centrifugal separator 11, separation mechanical seal 13, and discharge seat 20;

[0028] The separation spindle 19 is mounted on the separation bearing seat 14 via bearings, and is mounted on the machine body via the separation bearing seat 14. A separation mechanical seal 13 is provided at the connection between the separation spindle 19 and the machine body. The separation V-belt pulley 17 is fixedly mounted at one end away from the spindle 1 via a key connection or interference fit. The separation motor drives the separation spindle 19 to rotate via the separation V-belt pulley 17.

[0029] A centrifugal separator 11 is fixedly installed at one end of the main shaft 19. The centrifugal separator 11 is located inside the grinding chamber and a screen or gap channel is provided inside the centrifugal separator 11.

[0030] The discharge seat 20 is installed at the other end of the separating main shaft 19, and the separating main shaft 19 is a hollow structure. The centrifugal separator 11, the separating main shaft 19 and the discharge seat 20 are connected to form a discharge channel.

[0031] The specific working principle of the dual-power grinding and separation device in this embodiment includes:

[0032] Main drive power: After the main motor starts, it transmits power to the main shaft 1 through the V-belt pulley, which drives the pin rotor 9 mounted on the main shaft 1 to rotate at high speed, providing the core power for the grinding process.

[0033] Separation drive power: The separation motor drives the separation main shaft 19 to rotate through another set of V-belt pulleys, so that the centrifugal separator 11 installed on the separation main shaft 19 operates synchronously, providing power for the subsequent separation of materials and grinding media.

[0034] Grinding operation: The material and the grinding media in the cylinder enter the grinding chamber. Under the agitation of the high-speed rotating pin rotor 9, the solid particles in the material and the grinding media undergo violent collision, friction and shearing, which realizes the refinement of solid particles and disperses the aggregates in the material, thus achieving the purpose of fine processing of the material.

[0035] Separation and discharge: The ground material enters the centrifugal separator 11. Under the centrifugal force generated by the high-speed rotation of the centrifugal separator 11, the grinding media is separated and retained. The material that meets the requirements passes through the gap of the centrifugal separator 11 and is finally discharged from the discharge seat 20.

[0036] Furthermore, the grinding inner cylinder 8 and the grinding outer cylinder 10 are fitted with a clearance to form a cooling water circulation channel. The grinding inner cylinder 8 is provided with a cooling water inlet and a cooling water outlet that are connected to the cooling water circulation channel. Cooling water flows into the cavity between the grinding outer cylinder 10 and the grinding inner cylinder 8 from the cooling water inlet, circulates and carries away the heat generated during the grinding process, and then flows out from the cooling water outlet. The internal temperature of the device is kept stable through continuous circulation to avoid the grinding effect or equipment performance being affected by overheating. In addition, the grinding inner cylinder 8 and the grinding outer cylinder 10 are fixed by flanges or welding.

[0037] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use this application.
